Shipping took more than 2 months due to the current difficult circumstances but upon contacting Customer Service they said it would arrive within the next 6 days and it did ! The device seems to work as O2% declines while holding your breath for a long time and rises thereafter. Unfortunately without an external reference there is no means to calibrate it so you have to trust the readings as they come. Given the quality feel of the device I think it may accurate enough for home use by healthy persons. Disclaimer: if you have a medical condition requiring a certified accuracy you would need to get an approved device. The heart rate is spot on. The build quality is excellent and the device is easy and comfortable to use. OLED is bright, clean and can be rotated by button press to suit the readout position. Recommended to keep one in the house next to the thermometer and the blood pressure reader should the need arise.
